Question

What is the general electronic configuration of the outer shell of the elements from actinoid series?

Answer 1

Electronic configuration for the outer shell of elements in actinoid series:

1. The electronic configuration is basically the symbolic notation of the element in a manner in which the electrons are distributed in its atomic orbital and in a sequence.
2. So, Actinides are actually elements with atomic numbers from 90 to 103 following element: Actinium.
3. The symbol $\mathrm{Ac}$ is used for referring to any of the actinide series elements that range in the periodic table from the atomic numbers 89 to 103.
4. Also the elements in this actinoid series are radioactive in nature.
5. This Actinide series is the second one of the elements of f-block, having a terminal electronic configuration as: $\left[\mathrm{Rn}\right]5{\mathrm{f}}^{1-14}6{\mathrm{d}}^{0-1}7{\mathrm{s}}^2$
